Thread Repair & Reinforcement


Thread repair and reinforcement products repair and restore worn or damaged threads. Thread-locking inserts are used to repair stripped internal threads and have a locking element that reduces the effects of vibration. Thread repair kits offer the convenience of all necessary thread repair tools in one assortment. These kits often include threaded inserts, taps, drill bits, and ratchets.
